Add faster-coco-eval metric

[MiXaiLL76]

Motivation

Faster COCO Eval

https://github.com/MiXaiLL76/faster_coco_eval

This package wraps a facebook C++ implementation of COCO-eval operations found in the pycocotools package. This implementation greatly speeds up the evaluation time for coco's AP metrics, especially when dealing with a high number of instances in an image.

Modification

I added a variable (use_faster_coco_eval) to the CocoMetric class that allows you to select an additional type of validation, namely COCOeval_faster

Use cases (Optional)

For our use case with a test dataset of 5000 images from the coco val dataset.
Testing was carried out using the mmdetection framework and the eval_metric.py script. The indicators are presented below.

Visualization of testing colab_example.ipynb available in directory examples/comparison
colab_example.ipynb in google collab
Tested with rtmdet model bbox + segm

Summary for 5000 imgs

Type	faster-coco-eval	pycocotools	Profit
bbox	5.812	22.72	3.909
segm	7.413	24.434	3.296

Good library to speed up calculations

[BIGWangYuDong]

LGTM, kindly ping @hhaAndroid have a look

[MiXaiLL76]

Hello @hhaAndroid, I see that you are active on the site, please take a look at this PR

[MiXaiLL76]

@RangiLyu Maybe you’re here and the project hasn’t been abandoned yet?

[hhaAndroid]

I think it's best to make this dependency optional, to prevent affecting the previous usage pattern.
